Re: [pox-dev] wirshark plugin install error
Hi Rahul,
Thank you very much for your blog! I have made wireshark working on ubuntu
platform.
However, for my bug, I still have not yet figured out why this happens.
I want to give a description, can you help to look at it? I have sent the email
to Murphy.
My problem is :
On the switch side: I sent packet_in packets to pox controller. These packet_in
packets only buffer_id is different, others are the same. Buffer id starts from
0. use wireshark to capture the pacekts, I can find that on pox side, buffer id
also starts from 0. The attachment test_new.pcap I checked the capture result.
pox.txt is my test app pox log file. The following is my test app, you can see
I print out the buffer id. The buffer id starts not from 0, every test time the
buffer id starts differently. At the beginning, there are some warning
messages. If the buffer id starts from 263. The warning lines is 263 lines. I
do not why always some packet_in packets do not deliver to my test app. I have
no any idea how to track this problem deeply. Now I am waiting Murphy's reply.
I am newer to POX. Can you also help to look at it?
def _handle_PacketIn (event):
packet = event.parsed
msg = of.ofp_flow_mod()
msg.match = of.ofp_match.from_packet(packet, event.port);
msg.buffer_id = event.ofp.buffer_id
log.info("buffer_id %i", msg.buffer_id);
msg.idle_timeout = 10
msg.hard_timeout = 30
msg.actions.append(of.ofp_action_output(port = 0))
msg.data = event.ofp
event.connection.send(msg)
def launch ():
'''
Starting the Firewall module
'''
core.openflow.addListenerByName("PacketIn", _handle_PacketIn)
log.info("test miss flow")

Hi Zang,
You can follow the steps which I have written for ubuntu:

I have used the same bitbucket code as mentioned by Murphy. I hope it helps.

I'd suggest you may make your life easier by building Wireshark 1.10.7 from
source, then building the dissector against that.

By default, the wireshark does not have openflow.so and packet-openflow.so
plugins. So I think the official wireshark version I used does not support the
openflow. I will learn your build method and try it.

This might explain why you have both openflow.so and packet-openflow.so, which
seems strange to me offhand. The point being that you may not need to build an
OpenFlow dissector yourself at all.
If you do want/need to build a dissector yourself, you probably don't want to
use the one from the actual OpenFlow reference. The last time I built the
original dissector, it was from this updated version:
https://bitbucket.org/barnstorm/of-dissector
You might find more help on the openflow-discuss list.

Hello,
Are you using wireshark v.1.8 or more current version?

Re: [pox-dev] wirshark plugin install error
Wireshark is adding official support for OpenFlow. You may already have it.
This might explain why you have both openflow.so and packet-openflow.so, which
seems strange to me offhand. The point being that you may not need to build an
OpenFlow dissector yourself at all.
